Facile self-propagated carbonization synthesis of phosphorus-doped carbon-based catalysts for partial oxidation and hydrogenation

Abstract

In this work, fast self-propagated carbonization (SPC) method to prepare phosphorus-doped carbon (PDC) and hybrid materials is proposed. The PdZr/PDC prepared by the SPC method has good catalytic performance for...

Solvent-free aerobic photocatalytic oxidation of C(sp3)–H and C(sp3)–OH to CO bonds

“…1d, the FT-IR peaks at 400–800 cm −1 in the spectrum of Nb 2 O 5 –P are attributed to the asymmetric frequency of Nb–O–Nb. 31 In the case of C–Nb 2 O 5 , the peak at 3585–3345 cm −1 is recognized as the O–H stretching vibration and –COOH functional groups. 22 The peaks at 2874–2787 cm −1 are consistent with the asymmetric and symmetric C–H (–CH– and –CH 2 ) stretching.…”

Acceleration of the semi-hydrogenation of alkynes over an N-doped porous carbon sphere-confined ultrafine PdCu bimetallic nanoparticle catalyst

“…For instance, the introduction of heteroatoms such as N, S, and P into porous frameworks renders outstanding activity for catalysis and fuel-cell batteries. 23,[28][29][30][31][32] Heteroatomdoped mesoporous carbon with a regular channel structure can not only firmly anchor bimetallic active sites but also enhance mass transfer during catalysis. However, it is still difficult to fabricate regular heteroatom-doped porous carbon supports with large accessible pores, as well as novel structures, for developing efficient catalysts for the semi-hydrogenation of alkynes.…”
